MOTIVE POWER TAKING-OFF SHAFT OF WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To easily fit/install a driven side joint of a work machine by a spline in a short time by arranging a tooth having a tooth bottom diameter smaller than a tooth bottom diameter of the spline on the outer peripheral surface of the projecting part so that the tooth bottom of the tooth continues with the tooth bottom of the spline. SOLUTION: A tooth 4 having a tooth bottom diameter d2 smaller than a tooth bottom diameter d1 of a spline 2 is arranged on the outer peripheral surface of the projecting part 3 so that the tooth bottom 4a of the tooth 4 continues with the tooth bottom 2a of the spline 2 through the taper part 5 being an angleθof about 7 degrees to the axis of a motive power taking-off shaft. An operator can sense this state since the projecting part 3 strikes on a spline hole 10 when a spline shaft 10 of a joint 11 is inserted into the motive power taking-off shaft by moving the spline shaft in the arrow A direction in a state of slightly inclining to the motive power taking-off shaft, so that the joint 11 can be easily installed when the joint 11 is thrust in the state by adjusting the spline hole 10 to the tooth 4 of the projecting part 3 by slightly rotating the joint 11 in the second place.
